EX_BG is archaism from old integrated NFS code. The built-in NFS code

build-sys: add VARSUFFIX to UTIL_CHECK_LIB
The UTIL_CHECK_LIB macro follows the default autoconf behaviour and
generates have_<libname> and HAVE_LIB<LIBNAME> variables.
Some libraries are substitutional (e.g. ncurses and ncursesw). It would be
nice to generate for that libraries the same HAVE_ variables independently
on a library name.
This patch adds optional VARSUFFIX option to UTIL_CHECK_LIB, so the final
variables are have_<varsuffix> and HAVE_LIB<VARSUFFIX>.
For example:
UTIL_CHECK_LIB(yyy, func) generates have_yyy and HAVE_LIBYYY
UTIL_CHECK_LIB(yyy, func, xxx) generates have_xxx and HAVE_LIBXXX

The following patch makes the username-in-upper-case feature optional.
I have chosen to make it default to off since this feature was designed

fdisk: use more readable "GPT" name rather than "EFI GPT"
Although GPT is defined in EFI spec, it is widely used without EFI, as it

mkswap: set UUID for swap space (add -U option)

It's essential when partitions are to be recognised by their uuid and
not by their old device path anymore.

mount: "can't create lock file" message sometimes means failure, sometimes not
What the patch does is goes from the situation where:
1) If /etc/mtab doesn't exist and /etc is read-only, you get the
"can't create lock file" message and the mount fails
2) If /etc/mtab does exist and /etc is read-only,you get the same
message but the mount succeeds
Clearly, the failure to update /etc/mtab should either cause the mount
to fail or not ... sometimes causing it to fail, and sometimes not
(each with the same message) is not useful.
This patch sets the same behaviour for create and update mtab. In both
cases it prints error message and the mount succeeds.

Timezone handling is broken in this version since it's always

losetup: support unlimited number of loops
Old implementation:
- supports 256 loop devices only
- doesn't support gaps in list of loop devices
(e.g. loop0, loop1, loop3 -- loop3 is invisible)
Kernel 2.6.21 removes artificial maximum 256 loop device. Now the maximum
of loop devices could be really huge (depends on limit of MINOR
numbers). It means we need a better way how work with loop devices
than blindly call stat(2) for all 0-1048575 devices.
This patch uses three methods:
a) scan /sys/block/loopN (used for losetup -a only). This method is
probably the fastest way how found used loop device on machine with
huge number of devices in /dev.
b) classic way, stat(2) for all loop[0-7] devices (default number of
loop devices). This cheap method is sufficient for 99% of all machines.
