I'm giving it 4 starts because while studying this book I felt like an instructor was on my side telling me what to do, but there are lots of typos. Some were easy to figure out what to do and others I had a really hard time trying to complete the tasks and I've got more than 4 years of working experience with Linux.
I'll give you an example of a typo:
In the Chapter "File systems and Such" the author asks you to create a bunch of partitions by your own and one of them is LVM. The problem is that he doesn't say what's the name of the Physical Volume, Volume Group and how many Logical Volumes you should create.
One of the partitions created was /dev/hdb1 as EXT4 he asks you to label it as CData. Then he says you should mount it with the command "mount LABEL=CData /opt/company_data", OK, fine!
Then, he asks you to do some "file system check" at the LVM partition located in /dev/hdd. I had to figure out from the output of the commands that he was checking the integrity of the file system type EXT2 that belongs to the logical volume "lvol0"(?) inside of a volume group called "vg_group01" and I created the physical volume (named it myself), the volume group (vol_group01) and a logical volume called "lvol0" and used mkfs.ext2 to create the file system EXT2.
Finally, he says that you should MOUNT the filesystem previously checked but the mount command used is INCORRECT "mount LABEL=CData /opt/company_data". This is the same command of the previous "mount" task! So, where the hell am I suppose to mount the filesystem? Which command should I use? Ok, it's fine for me because I'm an experienced Linux sysadmin, so I created a directory by my own and mounted it anyway. Then he says that I could verify that the filesystem is mounted with the command "mount" but there is nothing showing up about the mounted Ext2 LVM in the output.
UPDATE: (May 4):
Another typo: on chapter 5 (networking) the Ethernet bonding configuration is wrong. I had to look up on the Internet to find out how to configure it. It asks you to edit the "ifcfg-bond0" with DEVICE="eth0" (should be DEVICE="bond0"), and on ifcfg-eth1/eth2 it's written SALVE=yes, but actually it's "SLAVE=yes".
UPDATE: (May 5): on chapter 6 on "Creating an RPM", there is something wrong. I followed step-by-step and in the end an error message is displayed:
[root@RHEL01 SPECS]# rpmbuild -v -bb /usr/src/redhat/SPECS/sample.spec
error: File /root/rpmbuild/SOURCES/mysample.tar.gz: No such file or directory
Also, before creating the sample.spec file, there is no mention that the file is named "sample.spec". I only figured that out because of the rpmbuild command later on.
Apart from that I recommend this book for people with at least 2 years of hands-on working experience in the Linux field, definitely not for inexperienced users.
