This is stupid SELinux disadvantage and SELinux should be fixed.
Note that mount(8) and libmount removes all selinux context options on
remount for kernels< 2.6.39 because SELinux context remount was
unsupported, so this SELinux disadvantage should be hidden for usual
use case.
Maybe we can also add another exception for SELinux to de-duplicate
the SELinux context options in the options string. It's not perfect,
but probably acceptable for SELinux -- I can do this for 2.22-rc2.
That would be great. What is your opinion on getting the SElinux options
handled differently in the kernel instead or in addition?
SELinux is no filesystem and we already have (must have) SELinux
specific code in mount(8) (and many others utils;-).
Okay, so as it's not a filesystem, it warrants the de-dup handling. I'd
appreciate it if this makes it in 2.22-rc2. Please let me know if you want me to
provide patches and/or test the results.
Many thanks,
Niels
