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.

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).

0c372549f6 Avoid the need for calling functions that malloc after a vfork(). 1998-10-11 14:11:51 +00:00
Bruce Evans
0890dc6f44 vfork -> fork. The child calls execl() which calls malloc(), so 
vfork() can't be used.  We could use alloca() in execl() so that
it can be called between vfork() and execve(), but a "portable"
popen() shouldn't depend on this.  Calling execle() instead of
execl() should be fairly safe, since execle() is supposed to be
callable from signal handlers and signal handlers can't call
malloc().  However, execle() is broken.
