[Devel] [PATCH] fused: save logrotate option to fstab

[Dmitry Monakhov]

currently one may run 'vstorage-mount -s' with -L option, but
it will affect only current mount w/o reflection to fstab opts.
In fact mount.fuse.vstorage already has parser for logrotate option, so
this patch makes this feature fully supported.
