In this case I could run the patch as root anyway I think.
Interestingly, starting pd from /opt/bootlocal.sh as root at startup will make Pd use all of the CPU and hence produce stuttering audio. When I change the corresponding line in /opt/bootlocal.sh to start as user tc sudo -u tc /home/tc/myPdStartupScript.sh Pd runs normally. > > This might be off-topic, but has anyone managed to create a persisntent > > home directory inside /dev/mmcblk0p2 (the ext2/3 partition created by > > piCore itself, which I did maximize already)? > > You can use the command `filetool.sh -b` to backup a snapshot of the homedir > to the SD card and it will be returned to that state on reboot. This is what I read from the docs and what I am currently using. Albeit, I am having a 300MB sound file in my home dir and it being part of the filetool.sh backup immensely slows down startup as the OS has to uncompress the audiofile. > There is also a kernel boot parameter to make the homedir persist > automatically: > > http://forum.tinycorelinux.net/index.php?topic=15450.0 This is the method I am trying to use with a directory inside /dev/mmcblk0p2 (the ext2/3 partition created by piCore itself, which I did maximize to the full available space on the memory card). Possibly I have to try to shrink that partition to make space for yet another partition as dedicated /home.
