since apt 2.1.16 we can use --error-on=any and do not anymore need to error out on all W: lines (closes: #6) 3 years ago
Benjamin Drung 0378c101bb
Pass extended attributes (excluding system) to tar2sqfs 
/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: handle ASCII-armored keyrings as well 
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.

Rework /dev, /sys, /proc mounting

 - 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

allow unshare as root user 
- this is useful when you are already root and want the benefits of
   unsharing the mount namespace to prevent messing up your system
 - if the unshare mode is used as root, the user namespace is not unshared
   anymore and newuidmap, setuid and friends are not called anymore
 - if the unshare mode is used as non-root test if the user namespace can be
   unshared, otherwise test if the mount namespace can be unshared

skip the emulation check in chrootless mode 
Whenever the selected architecture differs from the native architecture
of the system that runs mmdebstrap, mmdebstrap checks whether it can run
the selected architecture. In the majority of cases, this is good and
helps avoid difficult to diagnose issues. However when running in
chrootless mode, we don't actually want to run any binaries from the
target system. For that reason, the emulation check should be skipped in
chrootless mode.
