mount.fc defines file contexts for /usr/bin/mount.*, /usr/bin/umount.*
and /usr/sbin/mount\.zfs. These patterns are not consistent for two
reasons:
- some distributions use /sbin/mount... for other file systems that zfs.
For example Debian uses /sbin/mount.ntfs-3g
(https://packages.debian.org/jessie/amd64/ntfs-3g/filelist)
- mount_exec_t type should only be applied to mount, umount, mount.$FS
and umount.udisks2, not mountpoint.
Replace the file patterns with ones that do not match mountpoint and
match every mount and umount programs in /usr/bin and /usr/sbin.
Some policy modules define file contexts in /bin, /sbin and /lib without
defining similar file contexts in the same directory under /usr.
Add these missing file contexts when there are outside ifdef blocks.
Remove file context aliases and update file context paths to use the /run filesystem path.
Add backward compatibility file context alias for /var/run using applications like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783321
Lock files are still seated at /var/lock
