Current list is missing osmo-sip-connector.cfg. Let's just include the
whole directory.
Fixes: SYS#5632
Change-Id: Ia2376aaa8c5aae90ce00a86fe616a913ecaf025d
Since osmo-msc a2353c69cc3d2ccc7caee4571b3b8d2a98961150 and
osmo-bsc 3561bd48976dbee8dbd4659dad15be85a3e79ace osmo-bsc-mgcp support
is dropped in favour of osmo-mgw and one instance of osmo-mgw can be
shared between osmo-msc and osmo-bsc.
Move the default file list to a separate file in /etc/sysmocom/backup.d,
which is itself included in the backup. Also create a symlink to the
most recent backup.
Creating a new file in /etc/sysmocom/backup.d/ that ends with .backup
will be read during the backup and then be restored. This way we can
easily extend the files to backup.
* when restoring links e.g. for systemd files
the links will be created with content// prefix
* use transform instead of strip to remove
the "content/" prefix
* bump PR
Additional applications might store files in /etc/default and it
is the easiest to backup up all of them. This has the danger that
after an upgrade the default file is not compatible/optimal but
we will need to deal with that once it occurs.
