calls to code only called once in tee. Made BB_KLOGD and option.
-Erik
* kill now behaves itself properly, added 'kill -l' to list signals
* 'ls -l' was failing on long directories, since my_getid was leaking
one file descriptor per file. Oops.
- * Fixed rebooting from init. I'd left some debugging code in
+ * Fixed rebooting from init. I'd accidently left some debugging code in
which blocked reboots.
+ * Fixed reboot, halt (and added poweroff) such that they handle it when
+ init is not at PID 1 (like when running in an initrd).
* Added a prelinary du implementation. Some parameter parsing
stuff still needs to be added. -beppu (John Beppu <beppu@lineo.com>)
* Implemented tee. -beppu
* Allow tar to create archives with sockets, devices, and other special files
* Add in a mini insmod, rmmod, lsmod
-* Change init so halt, reboot (and poweroff) work with an initrd
- when init is not PID 1
-* poweroff
* mkfifo
* dnsdomainname
* traceroute/nslookup/netstat
* sort/uniq
* wc
* tr
-* expr (maybe)? (ash builtin?)
+* expr (maybe?) (ash builtin?)
* login/sulogin/passwd/getty (These are actully now part of tinylogin, which
I've just started to maintain).
