I found that thread by searching for mydata.gz. I tried to install the actual TC on an Acer Travelmate 220. I think that laptop is about 20 years old. I got it in the meantime after half a dozen trials with new formating the disk. The problem:
If I installed any additional program (i. e. kmap.tcz) I got the message, that a backup is impossible (or a kind like that) and I end in the command line after a restart.
I found that the file prepared by "touch /mnt/hda1/tce/mydata.gz" is not such, but it is a directory!!! I tried that 4 times and it reproduces. Dont ask me why - I do not know. I got TC running as I deletes the directory mydata.gz and did nothing more. In this case the setup and restart was successful. All that is abit misterious and after about a douzend different trials and about 5 hours I dont like to repeat that again! So I ask you to check this strange thing yourself. I tried touch with other parameters and found it working as expexted. May be tehre is another source for that problem?
Now TC runs like a charm with LYX, firefox and some compilers and I am very satisfied with my experiments- My first impression is absolutely positive.

PS: Ok, if you really need some more details to fix this "bug" (? eventualy) I am willing to deliver details by doing some more new installations.
