mke2fs hangs ?

[atze]

hy!
maybe i'm a little bit off-topic but a had no other idea where to post 
my prob.
i built a kickstart disk myself, using the 2.4.8 kernel, ramdisk, 
whatever, and everythings running wuite fine indeed.

my only problem is this: when executine the script below to initiate the 
hard disks, the script hangs. right after sfdisk partitioned the disk 
with the data from its input file, mke2fs shows it initial line (mke2fs 
1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09) and then stops.
to go on with the script one has to press any key, shift, tab, caps, 
whatever..

anyone has a clue what could cause that behaviour ?

thx to all
