eec1dbe6ce Make the implementation and documentation agree. Specifically: 
- document that sysctl() and sysctlbyname() return 0 on success

 - if the provided buffer is too small, set errno to ENOMEM and return -1
   instead of returning ENOMEM.

5b9e6e493e Fix grammar in the description of timegm() by totally rewriting it. Remove 
a potentally inflammatory comment from BUGS, and add a more useful comment
about the lack of reentrancy in the timezone-setting interface.

2e4513990b Ignore the fs_spec entry for "/" in /etc/fstab if the device which 
is actually mounted on "/" can be determined using statfs() and is
in /dev.  This fixes fsck operating on the wrong device when the
fs_spec entry is only an alias.  The aliased case became more
dangerous when the ROOTSLICE_HUNT hack was committed in mount(8).
ROOTSLICE_HUNT may be unnecessary now.

6b387220be [This is a null commit to supply the correct log entry] 
Rename 'cerror' to '.cerror' so that programs which have a function or
global variable named 'cerror' don't completely break the syscall error
reporting mechanism.

This is not yet a 'real' option but will be within some number of hours.

d529713846 Adjust for kern.ps_strings and PS_STRINGS not being a pointer. This is 
an unimprovement here.  I thought it would be an improvement, as in libkvm,
but here we can access the strings directly.

Use sysctlbyname() instead of sysctl() and trust it to give a nonzero
address if it succeeds.

86854f0360 A feeble attempt at kld compatability. The mount_* programs assume that 
they cannot mount a filesystem that they cannot see in getvfsbyname().
Part 1 of this is a hack, make vfsisloadable() always return true - the
ultimate decider of whether it's loadable or not is kldload() or mount().
Part 2 of this is to have vfsload() call kldload(2) and return success if
it works.  This means that we will use a viable kld module in preference
to an LKM!
Ultimately, the thing to do is remove the hacks to do a vfsload in all the
mount_* commands and let the kernel do it by itself in mount(2).
