'unknown filesystem type 'hfsplus'' while building on CentOS 7

[nmusatti]

While building the iso following the CentOS intructions I got this error message:

ERROR:program:mount: unknown filesystem type 'hfsplus' mount: unknown filesystem type 'hfsplus' Traceback (most recent call last): File "/sbin/mkefiboot", line 153, in opt.diskname) File "/sbin/mkefiboot", line 44, in mkmacboot mkhfsimg(None, outfile, label=label, graft=graft, size=size) File "/usr/lib/python2.7/site-packages/pylorax/imgutils.py", line 397, in mkhfsimg mkfsargs=["-v", label], graft=graft) File "/usr/lib/python2.7/site-packages/pylorax/imgutils.py", line 374, in mkfsimage with Mount(loopdev, mountargs) as mnt: File "/usr/lib/python2.7/site-packages/pylorax/imgutils.py", line 289, in enter self.mnt = mount(self.dev, self.opts, self.mnt) File "/usr/lib/python2.7/site-packages/pylorax/imgutils.py", line 176, in mount runcmd(mount) File "/usr/lib/python2.7/site-packages/pylorax/executils.py", line 414, in runcmd return execWithRedirect(cmd[0], cmd[1:], **kwargs) File "/usr/lib/python2.7/site-packages/pylorax/executils.py", line 179, in execWithRedirect raise subprocess.CalledProcessError(ret, [command]+argv) subprocess.CalledProcessError: Command '['mount', '/dev/loop3', '/tmp/lorax.imgutils.ALx0iT']' returned non-zero exit status 32

Building carries on apparently without further problems except that the removal of the grub2-tools.x86_64 1:2.02-0.44.el7.centos package fails.

Are these serious errors or can they be safely overlooked?

Yes, these are not serious errors and safely overlooked. These debug track you can also see in our centos CI => https://ci.centos.org/job/minishift-centos-iso/2/console
