For non-release builds the version will include the number of commits since last release and the commit hash with dashes, e.g. 1.20.8-46-g0881.
For downstream distros it seems it may include their identification strings, e.g. 1.20.9ubuntu2.
Make the regex match everything after the version number to avoid incorrectly erroring on such versions.
Fixes#18
* remove_tree() requires the CWD to be accessible or fails with
cannot chdir to $CWD from $DIR_TO_DELETE: Permission denied, aborting.
* CWD is not always accessible -- example: run mmdebstrap from a
directory only accessible by the current user (like a tempdir) in
unshare mode
* find from findutils *also* requires CWD to be accessible but it's
easier to temporarily change CWD in a subprocess because using
there is no utility in perl core that changes CWD temporarily and
cleans up after itself
* we need to use find from findutils instead of rm in unshare mode
because the root directory itself might not be removable by the
unshared user so we only want to remove its subdirectories
There are now systems with 160 cores (debci runs on two Ampere Altra
ARMv8 Neoverse-N1), which makes xz fail with: "xz: (stdin): Cannot
allocate memory"
- use /etc/ld.so.conf from the chroot instead of the host
- parse /etc/ld.so.conf instead of blindly accessing /etc/ld.so.conf.d
- add libraries from the chroot instead of the host
- instead of throwing an error, just print a warning
- can now run as root without cap_sys_admin
- can now run without mount installed
- --skip=check/canmount is not needed anymore
- gpg will not create a trustdb when running with --update-trustdb with
--trust-model=always:
gpg: no need for a trustdb update with 'always' trust model
- subsequent gpg calls will fail because there is no trustdb in GPGHOME
- use $REAL_USER_ID from English instead of $<
- use getgrgid $REAL_GROUP_ID to get the group name instead of assuming
the group name to be equal to the user name
- also check whether /etc/subgid exists and is readable
This is fixing the error:
cannot rmdir /var/lib/apt/lists/auxfiles: Directory not empty at ./mmdebstrap/mmdebstrap line 3084.
which happens when using apt-transport-mirror.
/bin/ping (from iputils-ping) uses the security capabilities to allow
users to use the program:
```
$ getcap /bin/ping
/bin/ping cap_net_raw=ep
```
Debian testing/unstable images (variant important) contain security and
system attributes:
```
$ mmdebstrap --variant=important bullseye root.tar
$ tar --xattrs --xattrs-include='*' -vv -tf root.tar | grep -B 1 '^ '
-rwxr-xr-x* 0/0 77432 2021-02-02 18:49 ./bin/ping
x: 20 security.capability
--
drwxr-sr-x* 0/102 0 2021-05-07 15:10 ./var/log/journal/
x: 44 system.posix_acl_access
x: 44 system.posix_acl_default
```
When generating a squashfs image with mmdebstrap 0.7.5-2, these security
capabilities are lost. Example for building a squashfs image in a
minimal Debian unstable schroot:
```
$ apt install -y mmdebstrap squashfs-tools-ng
$ mmdebstrap --variant=important buster root.squashfs
$ rdsquashfs -x /bin/ping root.squashfs
$
```
tar2sqfs from squashfs-tools-ng 1.0.4-1 supports encoding extended
attributes from the namespace `user`, `trusted`, and `security` (see
`include/sqfs/xattr.h`). GNU tar (version 1.34) supports these three
namespaces plus the namespace `system`.
Passing extended attributes from the `system` namespace to tar2sqfs will
produce an error:
```
ERROR: squashfs does not support xattr prefix of system.posix_acl_default
```
So pass the extended attributes to tar2sqfs, but exclude the `system`
namespace. Then ping will keep its security attributes:
```
$ rdsquashfs -x /bin/ping root.squashfs
security.capability=0x0100000200200000000000000000000000000000
```

gpg command "--list-keys" requires input files to be passed with
option "--keyring" and each file must match type "public keyring v4"
while gpg command "--show-keys" doesn't require extra options and
handles also ASCII-armored public keyrings as well.

- assume all entries in @devfiles to be in /dev
- allow for /dev, /sys and /proc not to exist in the target and print warning
- allow for /dev entries as well as /sys and /proc not to exist on the outside
- simplify umount by storing special options in @umountopts
- remove superfluous checks for root and unshare mode
- make sure /dev entries are less than 100 chars in size for tar
