- Problem on Debian/IA64 via LAN Console => no reaction on keyboard because of newt and dialog
- Only problem with mkCDrec v0.9.8 was the parted version. On RedHat Enterprise the layout of parted looks like: Disk geometry for /dev/sdb: 0.000-34732.890 megabytes Disk label type: gpt Minor Start End Filesystem Name Flags 1 0.017 100.002 fat16 boot 2 100.002 32740.452 ext3 32740.452 34732.873 linux-swap And on Debian/IA64 it looks: Disk /dev/sdb: 73.4GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 100MB 100MB fat16 boot 2 100MB 71.4GB 71.3GB ext3 3 71.4GB 73.4GB 2049MB linux-swap Needed to change rd-base.sh script to get a good partitioning file. Next release (v0.9.9) will have the updated code. For the rest no difference with RedHat (for booting and recovering).
