[Fedora-livecd-list] Two questions regarding livecd-creator

[Drew Weaver]

Hello everyone and happy new year.

I have two questions regarding livecd-creator:

When I try to use livecd-creator 27.1 on CentOS 7 1908 it always seems to fail like this:

Traceback (most recent call last):
  File "./tools/livecd-creator", line 258, in <module>
    sys.exit(main())
  File "./tools/livecd-creator", line 241, in main
    creator.package(ops=ops)
  File "/usr/lib/python2.7/site-packages/imgcreate/creator.py", line 829, in
package
    self._stage_final_image(ops)
  File "/usr/lib/python2.7/site-packages/imgcreate/live.py", line 382, in
_stage_final_image
    self.__create_iso(self.__isodir)
  File "/usr/lib/python2.7/site-packages/imgcreate/live.py", line 332, in
__create_iso
    if subprocess.call(args) != 0:
  File "/usr/lib64/python2.7/subprocess.py", line 524, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Does anyone know what specifically it's trying to do there?

Question 2:

When I use the version that is packaged with CentOS 7 (21.4-2.el7) (there is a bug with
selinux that prevents you from logging in but I worked around that problem)

It creates the ISO, I can convert the ISO to a PXE image and boot a machine from that
image.

However, once I write about 300MB of data to the / filesystem the filesystem goes
read-only even though the filesystem supposedly has 4GB of free space still.

The program that I am trying to run inside of my live environment apparently has no way to
write data to other paths, so I am sort of stuck.

Thanks,
