Hi,
I have cloned the latest source from the snapper git repo recently and use it to create and manage snapshots on thin volume created by dm-thin modules. Everything works perfectly until I want to allow users of group "Domain/Backup Operators" to create snapshot on this thin volume. I cannot set the ALLOW_GROUP parameter in the snapper config file to "Domain/Backup Operators", since snapper takes space as the separator between groups. Therefore, "Domain/Backup Operators" will be processed as two separate groups "Domain/Backup" and "Operators". Is it possible to allow such group in snapper config file?
Hi Teng-Feng,
right now it's not possible to have groups with spaces. According
to the groupadd manpage this is not allowed. But as I have just
learned via Samba you can get such group names.
Since you have compiled snapper from source you can change it. In
server/MetaSnapper.cc in line 190 change
boost::split(groups, tmp, boost::is_any_of(" \t"), boost::token_compress_on);
to, e.g.
boost::split(groups, tmp, boost::is_any_of(":"), boost::token_compress_on);
Then groups have to be split by ":".
Unfortunately I cannot simply make that change upstream as it
will break the configuration for other users. Please open an
issue on GitHub so that I can find a proper solution.
Regards,
Arvin
