I have integrated this in the initscripts-6.87-2mdk, could you test ?

If they are, then they are all broken. Try installing ash and linking it as /bin/sh instead of bash. Then, try and reboot. Good luck, you will have to reboot again with init=/bin/bash and relink bash as /bin/sh! IMHO, the scripts should either be fixed to work with any standard sh, or have their hashbang changed from #!/bin/sh to #!/bin/bash >If not, there could >be much optimization and clearing, because bash let you do many things >not used in standard scripts (like the above '&> x', instead of '>x 2>&1' ) IMHO, use bash-isms, as long as the script calls bash, and not sh.

How 'bout this: for (( try=0; try<10; try++)) do if [ "$(ip link show $1 up)" ]; then echo "Link is UP" break fi echo "Link is DOWN, rising..." ip link set $1 up &> /dev/null sleep 1 done It works but is bash specific. Are initscripts supposed to run under plain sh ?? If not, there could be much optimization and clearing, because bash let you do many things not used in standard scripts (like the above '&> x', instead of '>x 2>&1' ) If you find it useful, I can turn it into a general function like timed_retry attempts timeout what_to_do check_for_done TIA -- J.A.

[Cooker] initscripts and eth
Hi all... I have two little problem with current cooker initscripts. - /etc/sysconfig/network-scripts/network-functions::check_link_down() has a fixed timeout of 2 secs to wait the link getting up. I had to increase this to 3 o 4 to make my sis900 (eth on laptop) initalize correctly. With the default sleep, the card was reported as 'link down, check cable'. I will try to mess with bash and post a patch to turn it into a loop with a number of tries (10) for 'ip link set up' with 1 sec sleep in each. - This damned sis900 is capable to talk to the cablemodem at FullDX, but the autonegotiation does not work. I forced a /sbin/mii-tool -F 10baseT-FD in the same function as above. This can be a 'popular' scenario. Could you add a new variable, such as MIIFLAGS, in ifconfig-eth0, so as to do /sbin/mii-tool $MIIFLAGS >/dev/null 2>&1 || return 1 to override defaults, or force non autodetected options ?
