[Libguestfs] [libguestfs PATCH 1/2] generator/customize: document that "--selinux-relabel" checks for SELinux

[Laszlo Ersek]

The documentation currently says that the user should avoid passing
"--selinux-relabel" on the command line if the guest does not support
SELinux. However, the "is_selinux_guest" helper function in
"common/mlcustomize/SELinux_relabel.ml" already turns "--selinux-relabel"
into a no-op if some key SELinux files are absent from the guest, so there
is no need to caution the user.

This change is relevant because the subsequent patches will turn on
"--selinux-relabel" by default, and therefore "is_selinux_guest" will grow
in importance.
