The script shebang is 

#!/bin/bash

and should be  

#!/bin/sh

Otherwise, if bash isn't installed (as is generally the case on embedded
builds) dhclient fails with "file not found"

Not a biggie, but I thought you might like it logged.

Reopen with exact ebuild name and version; assuming that everyone uses some
weirdo busybox stuff plain doesn't work... No idea what's this about.

sorry. package is net-misc/dhcp-3.0.5

file is /sbin/dhclient-script

> assuming that everyone uses some weirdo busybox stuff plain doesn't work...

Charmed, I'm sure.

The script starts with "#!/bin/bash" which will break on any system that
doesn't have bash installed. On the other hand "#!/bin/sh" should work for
anything that's Bourne shell based.

That's a fair point, but on on embedded systems then udhcpc or dhcpcd would be
used as ISC's dhcp is very bloated :)

# ls -l /sbin/{dhcpcd,dhclient,pump,udhcp*}
-rwxr-xr-x 1 root root 358640 2006-11-06 09:29 /sbin/dhclient
-rwxr-xr-x 1 root root  38312 2006-12-19 12:01 /sbin/dhcpcd
-rwxr-xr-x 1 root root  60216 2006-06-16 16:39 /sbin/pump
lrwxrwxrwx 1 root root      6 2006-07-25 21:49 /sbin/udhcpc -> udhcpd
-rwxr-xr-x 1 root root  27672 2006-07-25 21:49 /sbin/udhcpd

Not entirely accurate - if bash is invoked by #!/bin/sh then it turns off all
non POSIX functions, which is a fair bit. Luckily dhclient-script doesn't use
any of that, so I'll update it in one of the ~ARCH versions.

Fixed in dhcp-3.0.5 and 3.1.0_alpha2
