Use consistent terminology for set-user-ID and set-group-ID bits.
There's much inconsistency in the pages. "suid",
"set-user-identifier", "setuid". Stick with one terminology,
"set-user-ID" and set-grout-ID, as suggested in man-pages(7).

In the majority of pages, pathnames are formatted as Italic,

are formatted as bold. This patch fixes a number of those

docs: renice(1): Remove obsolete BUGS text
Already at least as far back as util-linux 2.2, renice uses
getpriority(2) to fetch the process's old nice value. Thus,
the "problem" discussed in this BUGS note disappeared long ago.
This is trivially demonstrable:
$ sleep 100 &
[1] 24322
$ renice -n 5 24322
24322 (process ID) old priority 0, new priority 5
$ renice -n 10 24322
24322 (process ID) old priority 5, new priority 10
Rather than trying to explain the ancient problem (20 years old?),
just kill this text.

docs: renice(1): Rework discussion of unprivileged users,
The BUGS section describing the limitations on what an unprivileged
user may do to the nice value is outdated, given the kernel changes
that added RLIMIT_NICE in Linux 2.6.12. So, remove that text.
The revised details for modern Linux were partially covered in NOTES,
but there were also inaccuracies there (and the use of the word
"monotonically" was unneeded). In particular, the point is that
unprivileged users can only increase the nice value. There is no
restriction particular to the range 0..+19. So, for example, the
following scenario is possible:
1. Superuser sets the nice value of an unprivileged user's
process to -20.
2. The unprivileged user can now renice that process to (say) -10.

hwclock: don't check for permissions
The right place to verify user permissions is kernel. The current
situation is too strict (due to previous attempts to use hwclock as
suid that has never been supported).
Previously (and as documented in the manpage) the default policy
was SCHED_RR. Now it's implicitly SCHED_OTHER (0) as the value
is not initialized explicitly anymore.

mount: append inverting options for mount.<type> on "users"
If you call mount(8) as root, then we need to append inverting options
(if specified by fstab) for "user" and "users" to /sbin/mount.<type>
command line, because for UID=0 mount.nfs follows command line rather
than the fstab setting.
This has been originally implemented by commit a4c0cc75ff9744299f108c259efab1bd30c8007a for the old mount(8). The
same feature is supported by libmount, unfortunately for "user" only.
We need the same also for "users" to be backwardly compatible.
