Description Stephen Samuel 2003-04-30 19:35:43 EDT
Description of problem:
In /etc/sysconfig/network-scripts/ifup line 265:

    NUMDEFROUTES=`ip -o route | \
                  grep "^default" | \
                  awk '{ nlines++ } END { print nlines }'`
This is an inneficient/ silly use of awk. far better to
simply use `wc -c`   (wc is 1/10th the size of awk)

either that, or get rid of grep and change the third line
                  awk '/^default/{ nlines++ } END { print nlines }'`

The grep needs to go, yes. We can't use wc, it's on /usr.

Fixed in CVS, will be in 7.20-1.
