Missing /tmp after recovery (ubuntu with one big /)

[gdha]

• rear version (/usr/sbin/rear -V): 2.2
• OS version (cat /etc/rear/os.conf or lsb_release -a): ubuntu 16.04
• rear configuration files (cat /etc/rear/site.conf or cat /etc/rear/local.conf): BACKUP=BAREOS
• Are you using legacy BIOS or UEFI boot? BIOS
• Brief description of the issue: after recovery mkinitrd failed due to missing /tmp directory
• Work-around, if any:
  Edit script /usr/share/rear/prep/default/400_save_mountpoint_details.sh and as last line add:

echo "tmp 1777 root root" >> "$VAR_DIR/recovery/mountpoint_permissions"

Perhaps it would be enough to change the default entry in conf/default.conf from (for ReaR 2.3):

DIRECTORY_ENTRIES_TO_RECOVER=( )
to
DIRECTORY_ENTRIES_TO_RECOVER=( '/tmp 1777 root root' )

Thoughts?

Any missing standard FHS directory is unexpeced because in
prep/default/400_save_directories.sh
I intentionally implemented (at least I tried to)
that all standard FHS directories are always recreated.

@gdha
could you inspect your "rear mkrescue" and "rear recover" logs
why the standard FHS directory 'tmp' is not automatically
recreated in this case.

@jsmeix Fair enough - for ReaR 2.3 it is fixed then (via prep/default/400_save_directories.sh), but the script was different in rear-2.2.
But, the work-around I gave is good enough for now. Thanks for the feedback and I will close it again

@gdha
if you find the time I would appreciate it
if you could verify that it is really fixed
with current ReaR master code.
