Re: [Leaf-user] More questions about Datchstein CD 1.0.2 and pppoe
So, could I change the ramsize this way to get LEAF to boot up on a very low memory machine?

> - is it possible to change the root ramdisk size and still booting from the CD ?? Yes, but you have to burn a new CD, with a different boot-floppy image. NOTE: It *is* possible to change the size of the /var/log ramdisk, since that's created at runtime. You only need a new boot-floppy image if you have to change the size of the root ramdisk. > - I think that the behaviour of the cut command as changed It has > in previous versions of dachstein: > ping -c 1 some.dns.name | grep PING | cut -d" ():" -f 3 > returned only the ip address > 1.2.3.4 > in dachstein cd, the same command returns > (1.2.3.4): > > Any idea ?? The previous cut command was massively broken, and the fact that the above usage worked was an artifact of cut's mis-behavior. Try the above on a 'normal' linux system and you'll get an error...the delimiter for cut must be a single character...

[Leaf-user] More questions about Datchstein CD 1.0.2 and pppoe
Hi again A couple of questions: - is it possible to change the root ramdisk size and still booting from the CD ?? - I think that the behaviour of the cut command as changed in previous versions of dachstein: ping -c 1 some.dns.name | grep PING | cut -d" ():" -f 3 returned only the ip address 1.2.3.4 in dachstein cd, the same command returns (1.2.3.4): Any idea ??
