94 netdata will be installed in /opt/netdata

103 Do not wait for the user to press ENTER.

111 you have a broken pkg-config.

349 You many need to check these:
351 1. The package uuid-dev (or libuuid-devel) has to be installed.
353 If your system cannot find libuuid, although it is installed
354 run me with the option: --libs-are-really-here

358 If your system cannot find zlib, although it is installed

1208 apps.plugin needs privileges
1210 Since you have installed netdata as a normal user, to have apps.plugin collect
1211 all the needed data, you have to give it the access rights it needs, by running
1212 either of the following sets of commands:
1214 To run apps.plugin with escalated capabilities:
1216 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1217 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1218 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1220 or, to run apps.plugin as root:
1222 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1223 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1225 apps.plugin is performing a hard-coded function of data collection for all
1226 running processes. It cannot be instructed from the netdata daemon to perform
1227 any task, so it is pretty safe to do this.
